To form present simple tense sentences we use the base form of the verb (go, work, speak, study). But with the 3rd grammatical person in singular (he, she, it) the base form of the verb changes.

Para formar oraciones en tiempo presente simpe usamos la forma base del verbo. Pero con la tercera persona gramatical en singular, la forma base del verbo cambia.

• In general the third personal singular is formed by adding –s to the base verb. En general la forma singular de la tercera persona es formada al agregar –s al verbo base.

Work  ----->   He wants

Need  ----->   She needs

 Want  ----->   It wants

• If the base verb ends in ss, x, ch, sh, o, we add –es at the end of the base verb. Si el verbo base termina en ss, x, ch, sh, o, agregamos –es al final del verbo base.

Pass    ----->   He passes

Fix       ----->  She Fixes

Catch  ----->   It catches

Push    ----->   He pushes

Go       ----->   She goes

• If the base verb ends in a consonant + y, then replace the –y for –ies. Si el verbo base termina con una consonante + y, entonces se reemplaza la –y por –ies.

Fly   ----->   It flies

Cry  ----->   She cries

Subject + Auxiliary verb + not  + Main Verb + Complement (Sujeto + verbo auxiliar + negacion + verbo principal + complemento)

The verb Do is the most common auxiliary verb, instead of denying the main verb, we deny the auxiliary verb. The auxiliary verb comes always before the main verb. In the case of the third person in singular (he, she, it) we use Does instead of Do and the main verb turns back into its base form.

El verbo Do(Hacer) es el verbo auxiliar más común, en lugar de negar el verbo principal, negamos el verbo auxiliar. El verbo auxiliar viene siempre antes del verbo principal. En el caso de la tercera persona singular (él, ella, ello) utilizamos Does en lugar de Do y el verbo principal vuelve a su forma base.
